Subject: [PATCH 5/6] clk: qcom: Add support for PLLs with early output
Date: Mon, 11 Jul 2016 16:20:38 +0530 [thread overview]
Message-ID: <1468234239-28693-6-git-send-email-rnayak@codeaurora.org> (raw)
In-Reply-To: <1468234239-28693-1-git-send-email-rnayak@codeaurora.org>
Some PLLs can have an additional early output (apart from
the main and aux outputs). Add support for the PLL driver
so it can be used to initialize/configure the early output
